⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution via database functions.
Likely Case
Unauthorized data access and manipulation of real estate listings, user data, and system configurations.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-critical data.
🎯 Exploit Status

🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
1. Check vendor website for updates. 2. If no patch available, implement workarounds. 3. Consider replacing with alternative software.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameterized queries and input validation to the delete_amenity function in Master.php
Edit /reps/classes/Master.php to replace raw SQL with prepared statements
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: Block requests to /reps/classes/Master.php?f=delete_amenity with SQL patterns
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules
- Implement database user with minimal permissions (read-only where possible)
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: /reps/classes/Master.php?f=delete_amenity&id=1' OR '1'='1Check Version:
Check application files for version information or consult documentationVerify Fix Applied:
Test with same payloads and verify they are rejected or properly handled📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed delete_amenity requests with SQL patterns
- Database queries from unexpected sources
Network Indicators:
- HTTP requests to /reps/classes/Master.php?f=delete_amenity with SQL keywords
- Unusual database traffic patterns
SIEM Query:
source="web_logs" AND uri="/reps/classes/Master.php" AND query_string="*delete_amenity*" AND (query_string="*' OR*" OR query_string="*UNION*" OR query_string="*SELECT*" OR query_string="*--*" OR query_string="*;*" OR query_string="*/*")
